Phase1 or Phase 2 Head

Iv got both a mark2 phase 1 and phase 2 heads here,
i know the phase 1 cams have holes in but are there any other differences?

There the same weight, you can use either.

I do remember though that some heads have an extra water pipe around/behind (facing the firewall) the thermostat housing area. So check that as you may need to blank a hose.

The cam covers have different breather pipe's.

i did notice aswell that the inlet mani and cam cover breather were different so ill probably use the phase 2 cover and inlet
